Question

I HAVE AN 8 YEAR GE REFRIGERATOR (MODEL # TFX22KRDS, SERIAL # HZ226094). FOR THE LAST WEEK IT'S BEEN LOOSING IT'S COLD. THE TEMP IN REFRIG. IS 60 DEGREES, & THE FREEZER IS ABOUT 49 DEGREES. I CHECKED & CLEANEED UNDERNEATH THE UNIT, & IT WAS PRETTY DIRTY, BUT DIDN'T SEEM TO MAKE ANY DIFFERENCE. I VACUUMED THE COIL & IT'S FINNS. ALSO, ON THE BACK WALL OF THE FREEZER, THERE IS ABOUT I" OF FROST ON IT, FROM TOP TO BOTTOM. ANY IDEAS BEFORE I JUNK IT? THANKS, FRED
